Advanced Emergency Brake Assist

WARNING: This page is about a different car, the 2015 Jaguar XF, 2014 Jaguar XF, and 2013 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.

Advanced EBA uses adaptive speed control technology to provide preemptive control when sudden braking is required. The system is an enhancement of electronic brake prefill and emergency brake assist. The system can sense the possibility of a collision before the driver reacts through the brake pedal and can prepare the braking process even before the driver reacts and moves to the brake pedal, thus when the driver takes action, the braking system can respond to emergency braking more promptly, potentially avoiding a collision entirely, or mitigating the effects if a collision is inevitable. The system activates if the risk of collision increases after the forward alert warning is issued.

After a forward alert warning is displayed, the brakes are automatically applied gently in preparation for rapid braking and the EBA activation threshold is lowered. If the brake pedal is then pressed quickly then braking is fully implemented by the emergency brake assist system, even if the pressure on the brake pedal is light.

The system operates using signals from the radar sensor, based on proximity to and closing speed to the vehicle in front by monitoring forward traffic and obstructions with the radar sensor used by adaptive speed control. Through the positive brake-line pressure available from the HCU, it will apply a pre-charge of brake pressure even before the driver reacts. Thresholds for the entry to EBA are reduced so that the system functions earlier than it would without the data from the radar sensor.

Advanced EBA is available at speeds above 5 mph (7 km/h) and will function even when forward alert and adaptive speed control are switched off.
